Description
Technical field
This utility model relates to granulator transmission device, particularly relates to a kind of non-maintaining pressure roller assembly gland and pressure roller assembly.
Background technology
In pressure roller assembly, pressure roller is to be fixed in pressure roller shaft by roller bearing, in order to make the operating of equipment more smooth and easy, generally to add lubricating oil in the junction of each part, plays lubrication.Existing pressure roller assembly adopts sealing device sealing effectiveness difference to be easily damaged, substantial amounts of dust can be produced around when pressure roller assembly runs, owing to lubricating oil is liquid, long-time long running will flow out equipment, the abrasion making equipment strengthens, and dust also easily enters in pressure roller assembly, causing pressure roller assembly to burn, impact produces.
Summary of the invention
The purpose of this utility model is in that the shortcoming overcoming above-mentioned prior art, it is provided that a kind of simple in construction, good sealing effect, it is simple to install, long service life, can meet the non-maintaining pressure roller assembly gland of one and the pressure roller assembly of production requirement.
This utility model is achieved through the following technical solutions:
A kind of non-maintaining pressure roller assembly gland and pressure roller assembly, including pressure roller shaft, pressure roller shaft is connected with pressure roller by bearing, it is provided with back-up ring between bearing inside pressure roller, the both sides of described bearing are provided with gland, the side of pressure roller shaft is provided with nut and floor clip, and described back-up ring is two, and two back-up rings are arranged in the draw-in groove on pressure roller medial surface；The exterior arc surface of described gland contacts with pressure roller inwall, and the exterior arc surface of gland is provided with annular groove, is provided with O-ring seal in annular groove, and described O-ring seal and pressure roller inwall closely cooperate；The pars intermedia of described gland is provided with the annular protrusion of hollow, and described pressure roller shaft is arranged in the middle of the annular protrusion of gland, is provided with annular oil groove between exterior arc surface and the exterior arc surface of gland of described annular protrusion.
The quantity of the annular groove on described gland exterior arc surface is at least two.
The utility model has the advantages that: adopt the technical solution of the utility model better pressure roller assembly to be sealed; prevent oil leak and dust from entering inside pressure roller assembly; the lubricant effect making pressure roller assembly is better; extend pressure roller assembly service life; decrease disorderly closedown, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is gland structure schematic diagram in Fig. 1.
Detailed description of the invention
Embodiment: non-maintaining pressure roller assembly gland as depicted and pressure roller assembly, including pressure roller shaft 1, pressure roller shaft 1 is connected with pressure roller 5 by bearing 6, is provided with back-up ring 7 between the bearing 6 inside pressure roller 5, described back-up ring 7 is two, and two back-up rings 7 are arranged in the draw-in groove 8 on pressure roller 5 medial surface.The both sides of described bearing 6 are provided with gland 4, and the exterior arc surface of gland 4 is provided with annular groove 9, are provided with O-ring seal 10 in annular groove 9, and described O-ring seal 10 closely cooperates with pressure roller 5 inwall.The exterior arc surface of described gland 4 contacts with pressure roller 5 inwall, pars intermedia at gland 4 is provided with the annular protrusion 12 of hollow, described pressure roller shaft 1 is arranged in the middle of the annular protrusion 12 of gland 4, is provided with annular oil groove 11 between exterior arc surface and the exterior arc surface of gland 4 of described annular protrusion 12.The side of pressure roller shaft 1 is provided with nut 2 and floor clip 3.
The quantity of the annular groove 9 on above-mentioned gland 4 exterior arc surface is at least two.
Claims (2)
1. a non-maintaining pressure roller assembly gland and pressure roller assembly, including pressure roller shaft, pressure roller shaft is connected with pressure roller by bearing, it is provided with back-up ring between bearing inside pressure roller, the both sides of described bearing are provided with gland, the side of pressure roller shaft is provided with nut and floor clip, it is characterized in that: described back-up ring is two, and two back-up rings are arranged in the draw-in groove on pressure roller medial surface；The exterior arc surface of described gland contacts with pressure roller inwall, and the exterior arc surface of gland is provided with annular groove, is provided with O-ring seal in annular groove, and described O-ring seal and pressure roller inwall closely cooperate；The pars intermedia of described gland is provided with the annular protrusion of hollow, and described pressure roller shaft is arranged in the middle of the annular protrusion of gland, is provided with annular oil groove between exterior arc surface and the exterior arc surface of gland of described annular protrusion.
